Great service guys! I just discovered you this week. I find the lat lon lookup services to be extremely usefull.

I'm currently using the lat-lon lookup to get the timezoneid, as well as the weather service to get the weather station id.

I would like to use the current weather provided with this weather station data, but it appears you are using cached weather data for about 6 hours. Is this correct?

I'm looking at some data now that is was about 6 hours old, and then it refreshed with data that is about 1 to 2 hours old.

To really be useful current weather conditions need to be at the most, about 2 hours old. Preferable closer to 1 hour. Otherwise forcast data from 6 hours ago will be more accurate than the actual observations.

Also, looking at the international METAR data available from NOAA, it appears to be about 0-60 minuts old.

(Alternatively, is this just a bug?)

Edit:
It appers that it may be a bug, since it just updated the weather data again (1 hour later). This data is again about 2 hours old. This means the data is about 1 hour older than the NOAA data. Much better.

We update the weather data once per hour.
I have checked the log files for error messages and found some problems with character encodings. I have thus changed the import code to convert the METAR reports to ascii before importing.
